Abstract (en)

Provided is a software upgrading method for a distributed communication device, and the method includes: softwares are upgraded in sequence in the main control units and the line card, new and old versions of a software are enabled to run simultaneously, and the new version of the software is enabled to replace seamlessly the old version of the software so as to enter a running state through active/standby state inversion of the active main control unit and the standby main control unit as well as control of an active/standby running state of the new and old versions of the software on the line card. Further disclosed is a software upgrading system for a distributed communication device. By means of the technical solutions according to the disclosure, the software of the forwarding plane of the line card is upgraded as required so as to avoid unnecessary service interruption arisen from the software upgrading, thus improving reliability and availability of services, avoiding severe economic loss resulted from the service interruption and improving user experiences.
